I am new on Acoustic drums. I had Zildjian K promo pack first and I really didn't like them. I went to Thomann and Clemens took 3 hours and helped me to select this HiHat (and other crash and ride). I ESPECIALLY fell in love with these HiHat... They sounds great, are not expensive and I am playing them for a couple of weeks and every time they bring a smile on my face. So do give them a shot, they sounds great! I am also happy that I went for 15".
